With "frombody" attribute, parameter of Web Api method recieves null value while testing it with Postman

Question

Given below is my WebApi method, and I want to test it with Postman, but whenever I submit the request, myKey always contains the null value.

[Route("Complete")]
[HttpPost]
[Authorize]
public async Task<IHttpActionResult> Complete([FromBody]string myKey)
{
    // My logic
}

And this how I am submitting the request via Postman.

I have found many post suggesting how can we submit the data from Web but not a single one showing same using Postman.

Can you please guide me to get the value of myKey via Postman tool?

Answer 1

Pass just the value from the request body. When you add the [FromBody] attribute for a simple type parameter like string, the body will be read as string.
